Similarity structure in visual speech perception and optical phonetic signals.
A complete understanding of visual phonetic perception (lipreading) requires linking perceptual effects to physical stimulus properties. However, the talking face is a highly complex stimulus, affording innumerable possible physical measurements. In the search for isomorphism between stimulus properties and phoneticeffects, second-order isomorphism was examined between theperceptual similaritie...
متن کاملSimilarity structure in visual phonetic perception and optical phonetics
This study was undertaken to examine relationships between the similarity structures of optical phonetic measures and visual phonetic perception. For this study, four talkers who varied in visual intelligibility were recorded simultaneously with a 3-dimensional optical recording system and a video camera. Subjects perceptually identified the talkers’ consonant-vowel nonsense syllable utterances...

متن کاملRelationships Between Phonetic Features and Speech Perception —
This paper concerns the relationships amongst acoustic phonetic features of speech signals, perceived vocal effort, and speech clarity. It is presented from a statistical analysis of a good number of subjective testing on an anechoic speech corpus with 5 different vocal efforts, namely hushed, normal, raised, loud, and shouted, with an aim to map objective acoustic phonetic features onto subjec...
متن کاملExplaining the visual and masked-visual advantage in speech perception in noise: the role of visual phonetic cues
Visual enhancement of speech intelligibility, although clearly established, still resists a clear description. We attempt to contribute to solving that problem by proposing a simple account based on phonetically motivated visual cues. This work extends a previous study quantifying the visual advantage in sentence intelligibility across three conditions with varying degrees of visual information...
